IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 36,004, dated July 29, 1862.

To all whom it may concern:

Be it known that I, D. F. HUMPHREY, of Saline, in the county of Washtenaw and State of Michigan, have invented a new and Improved Plow; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a longitudinal section of my invention, taken on the line as :11, Fig. 3. Fig. 2 is a back view of the same. Fig. 3 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved plow of that class which are constructed entirely of iron and it consists, first, in an improve ment in the draft attachment, whereby the pitch of the plow may be regulated as desired and, second, in an improvement in attaching the standards and landside to the beam, whereby the relative position of the former to the latter may be regulated as desired for the purpose of giving the plow more or less land, as circumstances may require.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the beam of the plow, which is of cast-iron and of tubular form. The main portion of the beam is curved in the usual way, and has a rod, B, fitted in it, the back end of which is secured to the beam by a bolt, to, passing through an eye, I), at the back end of the rod, as shown clearly in Fig. 1. The front end of the rod B passes through a slotted plate, 0, which is secured to the front end of the beam A by a bolt, 0, passing through a slot, d, in the front end of the beam, as clearly shown in Fig. 1. By this arrangement it will be seen that the front end of the rod B may be adjusted higher or lower, and consequently the pitch of the plow regulated as desired, the draft-hook being attached to the front end of the rod B.

D represents the front standard of the landside, the upper end of which has a screw, E, fitted in it, which passes upward in a recess, 6, in the beam, and has a nut,f, on its upper end, by screwing up which the standard D is firmly secured to the beam. (See Fig. 1.)

F is the back standard, the upper end of which is provided with a horizontal plate, G, which is slotted longitudinally, as shown at g, and has a bolt, h, passing through it, said bolt also passing through a lip, t, at the back end of the beam A, and having a nut,j, on its upper end.

The back end of the beam A is curved downward, as shown in Fig. 1, and the standards and landside H are all cast in one piece, the latter having any proper mold-board attached to it.

By loosening the nutj of the bolt h the back standard, F, may be shifted laterally and adjusted either in line with the beam A or out of line with it, either to the right or left, so as to give the plow more or less land, as may be required, and the plow adapted to the 'draft of one or more horses, as may be required.

The parts described, with the exception of the rod B and necessary bolts, are all of castiron, and they constitute a cheap, economical, and durable plow, and also a light one, as the beam A, being hollow or tubular, possesses strength with lightness.

I do not claim, broadly, a tubular cast-iron beam for plows, for they have been previously used; but,

Having thus described my invention, what I claim as new, and desire to secure by'Letters Patent, is

l. The draft-rod B, fitted in the tubular beam A and passing through the slot 61 in the front end thereof, when arranged with the slide 0 and bolt a, substantially as and for the purpose set forth.

2. Attaching the standards I) F'of the landside H to the beam A by means of the screw or bolt E and the bolt h', the former being fitted directly in the beam A and the latter pass ing through an oblong slot, g, in the plate G of the standard F, and through a lip, i, at the back end of the beam,substantially as and for the purpose set forth.
